Abstract (en)
[origin: WO2019229339A1] The device (100) for compressing a low-pressure gas comprises: - at least one compression chamber (105) comprising: - a low-pressure gas inlet (110); - a high-pressure gas outlet (115); - a liquid inlet (120); - a liquid outlet (125); and - a piston (130) located between the gas inlet and outlet, on the one hand, and the liquid inlet and outlet, on the other hand; - a liquid movement means (135) positioned on a liquid circuit connecting a liquid outlet and a liquid inlet of a compression chamber; and - a means (165) for measuring the pressure of the gas inside the compression chamber and a circuit (160) for recirculating the gas towards the inlet of a compression chamber when the measured pressure is below a determined limit value.
